Fans of the "Archie" comics are excited to discover that The CW network is in the works of adapting the story of the Riverdale gang into a TV series, simply titled "Riverdale."

Early in the project, actor K.J. Apa has been cast to play role of Archie Andrews. A pilot episode has already been shown at San Diego Comic Con, with Luke Perry portraying Archie's father. The story was darker than what fans of the "Archie" publications were used to. Now, it seems like actor Raul Castillo will be joining the cast of "Riverdale," The Hollywood Reporter reported.

Castillo, who has been known for roles in Fox's "Gotham" and Netflix'z "Easy," will be playing the role of a visiting music professor named Oscar. His character will debut in the fifth episode of the TV series, according to CBR.

"Riverdale" seems to have a dark tone, which is much different than what fans of the comics are accustomed to. Showrunner Greg Berlanti seems have taken beats from the "Afterlife with Archie" comic run, with elements of mystery and possible dealings with the supernatural.

While fans may not be on the fence when it comes to the tone of the upcoming "Archie" TV adaptation, one particular bit of information seems to point that Berlanti may still take more themes from the comics into "Riverdale."

One of the bigger reveals in the comics series is Jughead being "asexual." Recently this year, Canadian writer Chip Zdarsky and artist Erica Henderson gave Archie's burger-loving friend, Jughead a makeover. This would give Berlanti the option of carrying the notion of Cole Sprouse's Jughead being asexual into the TV adaptation.

With the recent casting details, fans are now asking if they will ever get to see this series on TV. "Riverdale" Season 1 is schedule to premiere on The CW network in the first quarter of 2017, according to WaitWith.Us. But as far as a definite premiere date, there is still no information regarding it.
